WINDOW-CLEANING DEVICE.

Specification of Letters Patent.

Patented July 1th, 191?.

Application filed March 6, 1917. Serial No. 152,803.

T 0 all whom it may concern:

Be it known that I, ABRAHAM LAPnDEs, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful l/VindowCleaning Device, of which thefollowing is a specification.

The present invention appertains to window cleaning devices and aims toprovide a novel and improved appliance of that nature applicable tovarious windows, and 0p erable conveniently from the inside of thebuilding for cleaning the outer as well as the inner surfaces of thewindow panes, thus eliminating the necessity of the person cleaning thewindow leaning or sitting through the opening, and thereby eliminatingthe possibility of the operator falling.

It is the object of the invention to provide a window cleaning devicewhich can be placed within the window opening when the sashes areraised, and into which the sashes can be lowered to readily clean thepanes, the device being readily applied to various windows and havingnovel rotary means for washing and wiping the window panes.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

The invention is illustrated in the accompanying drawings, whereinFigure 1 is an elevational view of the cleaning device as seen from theinside of the window.

Figs. 2 and 3 are vertical sections taken on the respective sectionlines 2-2 and 33 of Fig. 1.

Fig. 4 is a horizontal section taken on the line 44 of Fig. 2.

Fig. 5 is an enlarged cross section of one of the rotary washing andwiping members.

The frame of the present device is preferably constructed of sheet metaland structural iron, and may be of any suitable size and materials. Thisframe embodies outer and inner upstanding sections 1. and 2, re

about a transverse axis.

spectively, and a sheet metal or equivalent base 3. The lower end of thesection 1 is riveted or otherwise secured firmly to the base, while thelower end of the section 2 is hlnged, as at 4, to the base whereby theinner section 2 can be swung a limited distance away from the section 1.The base 3 is provided with a longitudinal depressed portion providing agroove or channel 5 between the lower ends of the sections 1 and 2 forreceiving the lower rail of the sash 6, as seen in Fig. 2, the sections1 and 2 being spaced apart sufliciently to receive the sashtherebetween.

Each of the sections 1 and 2 is provided with parallel vertical stiles,each stile embodying a pair of parallel T-irons or bars 7, and the guidebars 7 of each section are connected at their upper ends by a crosspiece or yoke S. Slidable between each pair of guide bars 7 is a blockor bearing 9, which is grooved to engage the webs of the bars 7, eachsection 12 having a pair of the hearings or slides 9 movable verticallywithin the stiles thereof. The bearings 9 are provided with pivot studs10 projecting toward one another, and a rotary washing and wiping memberis mounted between and is carried by each pair of bearings 9. Each ofsaid members embodies a transversely elongated cylindrical waterreservoir 11 provided at its ends with sockets 12 receiving therespective studs 10, whereby to mount the reservoir for rotary movementThe reservoir is provided with a plurality of longitudinal instruckchannels 13 in its periphery in which rubber or equivalent squeegees 14are seated. Said Squeegees are flexible and are adapted to bear againstand wipe along the surface of a window pane, and one squeegee 1 1 ofeach reservoir is provided with a suitable number of water outlet ducts15 registering with water outlet apertures 16 with which the respectivechannel 13 is provided, as seen in Fig. 5. Thus, when the reservoir isrotated, the water contained therein can flow through the apertures 16and ducts 15 to be applied to the window pane, so that the squeegeeswill serve to wash and wipe the same.

As a means for moving the reservoirs 11 vertically along the windowpane, cords 17 are connected to the bearings 9 and eX- tend. upwardlytherefrom and over pulleys or guides 18 suspended from the yokes 8. Fromthe pulleys 18 the cords 17 extend downwardly along the respectivestiles of the sections 12 and pass under pulleys or guides 19 carried bythe base 3. Similar cords or flexible elements 17 are also connected tothe bearings 9 and extend downwardly under pulleys or guides 19 mountedwithin the base 3. The cords extend under the channel or groove 5 fromone section of the frame to the other, and it will be noted that theintermediate portions of the cords 17 extend in loop form downwardly tothe base so as to pass under the sash. I Vhen the bearings 9 of thesection 2 are raised, this will pull the cords 17 which will pull thebearings 9 of the outer section 1 downwardly, and when the bearings 9 ofthe sec tion 2 are lowered, this will pull the cords 17 which will raisethe bearings 9 of the section 1. The bearings and reservoirs at theouter and inner sides are therefore moved in opposite directionssimultaneously.

In order to rotate the reservoirs or rotary cleaning memberssimultaneously at the different positions thereof, an endless sprocketchain or equivalent member 20 is trained around the reservoirs ormembers 11 near one end thereof, and said chain extends downwardly fromthe reservoirs into the base 3, and is guided under pulleys or guides 21mounted within the base from one section of "the frame to the otherunder the channel or groove 5, as seen in Fig. 2. When one loop of thechain is raised with the reservoir, the other loop is lowered, wherebythe chain will remain taut, due to the fact that the two reservoirs movein opposlte window are raised, and the device is then placed within thewindow frame on the sill thereof, the base 3 resting on the sill, andone sash is then lowered between the sections 1 and 2, the section 2being swung inwardly to facilitate the lowering of the sash. After thesash islowered into place, as seen in Fig. 2, the section 2 is swungagainst the sash, and the reservoirs can then be rotated as abovedescribed, for cleaning the window pane, and said reservoirs are raisedand low-.

ered to clean the window pane from top to bottom. After one sash hasbeen cleaned, it is 'aised, and the device is shifted slightly so thatthe other sash can be lowered into it for cleaning. When the sashes areraised, the device is readily removed and applied to another window, andit will be noted that it is not necessary for the operator to reach,lean or sit through the window for cleaning the outer surfaces of thewindow panes, thus avoiding danger to life and limb.

Having thus described the invention, what is claimed as new is 1. Awindow cleaning device embodying a frame having spaced upstandingsections for receiving a sash therebetween, bearings slidable along saidsections, cleaning members movably carried by said bearings, a

flexible connectionbetween the bearings for reciprocating them, and aflexible connection between the cleaning members for moving themrelatively to the bearings at the various positions thereof.

2. A window cleaning device embodying a frame, bearings slidable alongthe frame,

a rotary reservoir between and carried by said bearings, squeegeescarried by the reservoir, one of the squeegees having means for the flowof water from the reservoir, means for sliding said bearings, and meansfor rotating the reservoir.

3. A window cleaning device embodying a frame having spaced sections forreceiving a sash therebetween, bearings slidable along said sections,rotary members car-' ried by the bearings having Squeegees, flexibleelements connecting said bearings of the two sections, and a flexibleconnection between the rotary members. I

4:. A window cleaning device embodying a frame having a base and spacedsections connected thereto, bearings slidable along said sections,rotary members carried by the bearings and'having squeegees, flexibleelements connecting said'bearings and extend ing along said sections tothe base and guided within the base from one section to the other, andan endless flexible element passed around said rotary members and ex-.tending through and guided within the base from'one section to theother. g

In testimony that I claim the foregoing as my own, I have hereto aifixedmy signature in the presence of two witnesses.
